How can you tell if a region or country is too crowded?

A region or country may be considered too crowded if it consistently experiences high population density, leading to strained resources and infrastructure. Indicators include traffic congestion, inadequate housing, limited access to healthcare and education, and environmental degradation. Additionally, high levels of pollution and decreased quality of life can signal overcrowding. Surveys and studies assessing residents' satisfaction and well-being can also provide insights into whether an area is overcrowded.
